bad headgasket as suspected.. pics inside...

heres links to the 2 photos i have, there is carbon built up on the gasket, head and block, between cylinders 3 and 5. they both had poor compression 3 had 80psi 5 had 30psi.
hopefully the engine block is ok, because i am replacing the cylinder heads with new ones and i dont want to have the block decked. what do you guys think about using a fine emery cloth to remove all the old gasket adhesive that wont come up with a scraper?

Classic example of head asket failure. Wire wheel works faster.

Do not use any gasket adhesive or any other type of goop on composition type head gaskets. This may have contributed to your failure. Make sure all gasket sealing surfaces are straight, smooth, clean and dry. Clean the threads on the head bolts and the block with a good thread CHASER, not a tap and die. Make sure that the bolt holes in the block are clean (especially the blind holes), put a very tiny amount of thread sealer around the threads, about 1/4 of the way from the bottom of the bolts. A small amount of oil under the heads of the bolts, then torque to engine manufacturer's spec (and no more) in several sequences. Follow these procedures and you will have no "gasket failures" (aka installer mistakes).
